Assuming you set MaxBarsBack to 20, then at CurrentBar = 1, you 
have 20 bars of Close data.  That is the FIRST bar where your 
indicator is called, so it's the first bar where you can compute 
your transformation on Close.  You cannot have a value of Value1 
before CurrentBar = 1.

So if you want a 20-bar average of Value1, you have to set MBB to 
20 and do something like this:

Value1 = <whatever>;
if CurrentBar > 20 then begin
  Avg = average(Value1, 20);
  ...
end;

You *can't* calculate Avg any sooner than bar 41, because you 
need 20 bars of Value1, and you can't start calculating Value1 
until bar 21 (when CurrentBar = 1 and bar > MBB), because you 
have to set MBB to at least 20 so you can look back 20 bars for 
your average.

Who cares about the first 40 bars anyway?  Just make your chart 
longer and don't pay attention to the first bit.
